SAA7220 N.O.S Switch

N.O.S. apdaterboard switch simple between N.O.S. and O.S.

  • Switch between Non Over Sampling and Over Sampling
  • Digital Output keeps working
  • Muting keeps working

 

Some Measurements

Source Digital in 16 bits undithered frequentie. sweep 20Hz to 20kHz , AES 17 filter,

Non oversampling is 1 dB more

Level NOS and OS are  both 0 dBfs is 0 dBref – Source Digital in 16 bits undithered frequentie. sweep 20Hz to 20kHz , AES 17 filter

Level NOS and OS are  both 0 dBfs is 0 dBref – Source Digital in 16 bits undithered frequentie. sweep 20Hz to 20kHz , AES 17 filter

White noise , 16 bits undithered , sample at 192kHz , FFT 1m 10x average
